Hugging Bay
Open model files with recorded SHA-256 and licence labels. Ask for what's missing.

Quality & Safety
A
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
~11,119Tokens (tool definitions)
~3.6 KBTypical response size
Significant attention impact (8.69% of 128k context)
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢search_artifacts(q, limit, cursor, sort, type, ...)
Keyword search over model and dataset records, with task, licence, size and format filters, when you have no exact name; returns ids and short summaries. Use when you need keyword or filtered catalog results without an exact model name. Example: {"q":"embedding","limit":5}. Reads records; does not change files.

}🟢get_model(id, quant)
One model's licence, download readiness, main file, SHA-256, size and RAM estimate, plus runKit tested commands when Hugging Bay has run that exact file. Use when you have a model id and need its short file, licence and hardware summary. Example: {"id":"hf-model-qwen-qwen3-0-6b-gguf"}. If unavailable, read the retry guidance and the model's metadata or file-plan links.

One model's file inventory with paths, sizes, SHA-256 and hosting, plus runKit tested commands when Hugging Bay has run that exact file.
